I recently built this procedural wood shader for cycles 4D. It is based on a shader built for the blender community by Gabriel de Laubier. Hope it's useful for everyone. It works with the principled shader, so just connect it up and run with it!

Sorry to post it here, but my last messages just sits in the outbox, don't know why.
I can't find that original c4d file in my mess But found a screenshot which I've used to make it.
So I quickly reproduced it again for you.
